在jsp中怎样获得input元素的属性
例如: 
  <body>  
  <form   id= "Form1 "   method= "get "   action= "servlet1.do ">  
  <input         type= "text "         maxlength= "10 "         size= "20 "      value= "sadfasdfa "   name= "T1 "      id= "T1 "/>  
  <button   >  
 <jsp:setProperty   name= "type "   property= "submit "   /> ok </button>           
  </form>  
 test:${T1.size}   
  </body>  
  </html>  
 问:怎样获得T1的size属性???着急
------解决方案--------------------Form1.getT1();就可以了吧
------解决方案-------------------- <script>  
 alert(document.Form1.T1.size); 
  </script>    
 或者试试document.Form1.T1.offsetWidth;
------解决方案--------------------用input hidden来保存提交.
